Sibyl 0.3.0

Sibyl 0.3.0 turns the keyless retrieval path into a versioned, provenance-aware evidence provider for agent pipelines.

Highlights

• SourceBundle 1.6 with stable source and passage IDs, hashes, offsets, timestamps, publication metadata, and explicit failure states
• local lexical ranking with optional FlashRank and truthful fallback diagnostics
• evidence sufficiency, content-origin, content-cluster, and diversity signals for safer synthesis
• SSRF-resistant pinned networking, redirect validation, and bounded response bodies
• deterministic offline retrieval, pipeline, source-quality, and contract regression suites
• PyPI Trusted Publishing workflow with tag/version checks and clean-install validation
